  Log Message:
  -----------
  [FuncAttrs] Don't infer `noundef` for functions with `sanitize_memory` attribute (#76691)

MemorySanitizer assumes that the definition and declaration of a
function will be consistent. If we add `noundef` for some definitions,
it will break msan.

Fix buildbot failure caused by #76553.
